Overview

Module aims and purpose

Programming is a core skill in Computer Science. Building on the previous semester’s module on Imperative Programming, this module introduces Object-Oriented Programming (OOP), which is the dominant paradigm in modern software development. This module will introduce Java’s object-oriented features, such as classes, methods, interfaces, inheritance and generics. 

Objects make it easier to write programs in a modular way, which is advantageous when working on larger projects or as part of a team. Therefore the focus of this module will be on more complex problems, where the solution will usually involve writing several classes and using APIs from Java’s standard library. Students will use an edit-compile-run cycle when developing programs. 

On the conceptual side, the module will introduce principles for decomposing a large problem into smaller classes, including some common design patterns in OOP. Students will also be able to demonstrate their abilities in using Git for storing software, demonstration / presentation skills.

Module learning outcomes

By the end of the module, it is expected that students will be able to: 

1. Decompose a problem into multiple classes, recognising and applying common design patterns, showing the resulting design as a class diagram
2. Write, compile, run, test and document a Java program that implements the design shown in a class diagram
3. Justify or critique an OOP design using concepts such as encapsulation, polymorphism, abstraction and inheritance
4. Use external libraries to reduce development effort, reading API documentation as necessary

Module content

Features of Java beyond imperative programming: 

• Classes, objects, methods, properties, “new”, packages 
• Interfaces, inheritance, dynamic dispatch/subtype polymorphism 
• Generics/parametric polymorphism 
• ���泦���پ��DzԲ���
• �ճ���𲹻����

Common Java APIs: 

• Collections: List, Set, Queue, Map 
• GUI/graphics programming: Swing or JavaFX 

OOP design: 

• Encapsulation, abstraction and polymorphism 
• Class diagrams 
• Common design patterns 

Software development: 

• The edit-compile-run cycle 
• Working on a project with multiple source files in a programmer’s text editor or IDE 
• Reading API documentation and compiling with external libraries 
• Merging code with git 
• Writing unit tests with JUnit 

Topics covered lie mainly within the ACM Computer Science Curricula 2013 knowledge area “Programming Languages”, especially “Object-Oriented Programming” and “Event-Driven and Reactive Programming”. There is some coverage of other knowledge areas, such as “Software Engineering”. 

Structure

Teaching and learning methods

The module will introduce programming language concepts through lectures. Students will then be able to apply these concepts in practicals. 

Compared with the Imperative Programming module, new programming language concepts will be introduced through a smaller number of more complex examples and small projects. The APIs covered will be used to provide examples of some of the OOP concepts. For example, the Collections API illustrates both subtype and parametric polymorphism, while GUI libraries typically illustrate many design patterns, such as Factory and Observer. One of the projects will provide an opportunity for students to work in groups, so they get some experience of teamwork, both from the social perspective and the technical perspective. 

The start of the module will include an orientation session, where students will set up a suitable development environment, for example in IntelliJ or VS Code. 

Study hours

At least 28 hours of scheduled teaching and learning activities will be delivered in person, with the remaining hours for scheduled and self-scheduled teaching and learning activities delivered either in person or online. You will receive further details about how these hours will be delivered before the start of the module.

Please note the independent study hours above are notional numbers of hours; each student will approach studying in different ways. We would advise you to reflect on your learning and the number of hours you are allocating to these tasks.

Semester 1 The hours in this column may include hours during the Christmas holiday period.

Semester 2 The hours in this column may include hours during the Easter holiday period.

Summer The hours in this column will take place during the summer holidays and may be at the start and/or end of the module.

Assessment

Requirements for a pass

Students need to achieve an overall module mark of 40% to pass this module.

Summative assessment

Penalties for late submission of summative assessment

The Support Centres will apply the following penalties for work submitted late:

Assessments with numerical marks

• where the piece of work is submitted after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for that piece of work will be deducted from the mark for each working day (or part thereof) following the deadline up to a total of three working days;
• the mark awarded due to the imposition of the penalty shall not fall below the threshold pass mark, namely 40% in the case of modules at Levels 4-6 (i.e. undergraduate modules for Parts 1-3) and 50% in the case of Level 7 modules offered as part of an Integrated Masters or taught postgraduate degree programme;
• where the piece of work is awarded a mark below the threshold pass mark prior to any penalty being imposed, and is submitted up to three working days after the original deadline (or any formally agreed extension to the deadline), no penalty shall be imposed;
• where the piece of work is submitted more than three working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.

Assessments marked Pass/Fail

• where the piece of work is submitted within three working days of the deadline (or any formally agreed extension of the deadline): no penalty will be applied;
• where the piece of work is submitted more than three working days after the original deadline (or any formally agreed extension of the deadline): a grade of Fail will be awarded.

The University policy statement on penalties for late submission can be found at: /cqsd/-/media/project/functions/cqsd/documents/qap/penaltiesforlatesubmission.pdf

You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.

Formative assessment

Formative assessment is any task or activity which creates feedback (or feedforward) for you about your learning, but which does not contribute towards your overall module mark.

Students will be able to get immediate feedback on some of the practical exercises through use of an automated marking system. There will also be formative online multiple-choice tests for students to check their understanding of factual knowledge covered.
